Qualifications

There are a ton of great Python projects out there, but what makes an
application "Awesome™"? Please check that all of the following criteria apply:

• Free software with an online source repository.
• Using Python for a considerable part of their functionality.
• Well-known, or at least prominently used in an identifiable niche.
• Maintained or otherwise demonstrably still functional on relevant platforms.
• An application, not a library or framework.

Note that installability via pip/PyPI and a developer-audience focus
may warrant a higher standard for inclusion, in keeping with the
spirit of the list:
